Abstract

PURPOSE:To adjust automatically a feed rate of a material, by equipping a metering channel and a metering plunger between a material feed hopper and a material metering channel. CONSTITUTION:The metering channel 15 and the metering plunger 17 are equipped between the material feed hopper 10 and the material channel 11, and the motion of the metering plunger 17 is synchronized with that of the injection plunger 5, in the injection machine wherein materials fed from the material feed hopper 10 are pushed into the interior of the heating cylinder 2 and molten to be extruded from the tip of the cylinder.
